T 0 all whom it may concern:

Be it known that I, ALBERT J. PLUMMER,

acitiz'en of the United States, and residing at New York, in the countyof New York and fitate ofNew York, have invented certrain new and usefulImprovements in Photographers Printing-Masks, of which the following isa specification, such as will enable those skilled in the art to whichit appertains to make and use the same. This invention relates to masksor frames used by photographers and others in printing from negatives onsensitized cards or paper, and the object thereof is to provide animproved device of this class into which a negative and a sensitizedcard or a sheet of paper of predetermined form and dimensions may bequickly and easily inserted and securely held therein, while theprinting is being done, in an ordinary frame such as a blue rint frameor similar device; a further ob ectbeing to provide a mask or frame ofthe class specified by means of which a uniform margin of predetermineddimen sions will be formed entirely around the picture printed on thecard or paper, and with these and other objects in view the inventionconsists in a device of the class specified constructed as hereinafterdescribed and claimed.

The invention is fully disclosed in the following specification of whichthe accompanying drawing forms a part, in which the separate parts of myinvention are designated by suitable reference characters in each of theviews, and inwhich Figure 1 is a back view of my improved photographersmask or frame;-Fig. 2 a front view thereof ;-Fig'. 3 a view similar toFig. 2, but showing the sensitized card or paper and the negative bothin position in the mask or frame ;-Fig. 4 a section on the line 44 ofFig. 3, and on an enlarged scale ;Fig. 5 a section on the line .5-5 ofFig. 3, and on an enlarged scale, and Fig. 6 a fragmentary View similarto Fig. 3, but showing a modification.

In the practice of my invention I provide a mask or frame a composed offibrous material such as card board, and also composed of two sheets band c, and the sheet b is provided with a central-rectangular opening 1)and the sheet 0 with 2. correspondmg opening 0 of less dimensions thanthe opening 6 whereby a flange a is formed which extends entirely aroundthe central opening d in the mask or frame formed by the openings 5 andc in the separate parts I) and c of said mask or frame.

The back of the mask or frame is provided at the corners with triangularkeepers e which are pasted or glued thereto in such manner as to leaveor form pockets 6 designed to receive the corners of a negative f,which, in practice, is placed on the back of the mask or frame, asclearly indicated in the drawing, and which is securely held in thepockets 6 of the keepers e and the dimensions of the negative f arealways greater.

than thedimensions of the central opening in the part c of the mask orframe.

The sensitized card or paper 9 on which the picture or print is to beformed is of the Patented Feb. 4,1913.

same dimensions as the opening in the part b of the mask or frame, andwhen placed in position said card or paper fits in said opening, asclearly indicated or shown in the drawing. and the thickness of the cardor paper 9 is preferably such as to correspond with the thickness of thepart b of the mask or frame.

'hen the negative and the sensitized card or paper have been placed inthe mask or frame, the process of printing is proceeded with in theusual manner, and this may be done in a frame similar to the well knownblue printing frame, or any other device of this class.

In the modification shown in Fig. 6, 'the keepers e are providedcentrally of their diagonal edges with the recesses e which facilitatethe insertion of the corners of the negative f into the pockets 6 ofsaid keepers, and this is the only difference between the constructionshown in Fig. 6, and that shown in Figs. 1 to 5 inclusive.

It will be understood that the difference in the dimensions of theopenings 17 and c and the separate parts of the mask or frame form agroove or space which extends entirely around the central opening insaid mask or frame, and the dimensions of which determine the width ofthe: margin around the printed card or sheet, and the width of thismargin may be regulated by increasing the width of said groove or space,as will be readily understood, and it wilt also be understood that myimproved mask or frame may be made up in different sizes. or in any sizeto correspond with the various styles and classes of cameras now in use.

My improved photographers mask or frame may be made of any suitablematerial,

and While I have shown the central open-,

ing therein as rectangular in form, it will be understood that otherforms for said opening may be adapted, and other changes in andmodifications of vthe construct-ion herein described may be made, withinthe scope of the appended claim 'Without departing from the spirit of myinvention or sacrificing its advantages.

Having fully described my'invention what I claim as new and desire tosecure by Letters Patent is A photographers mask consisting of a framesheet of thin opaque material provided with a central opening aroundwhich Copies of this patent may' be obtained for five cents each, byaddressing the Commissioner of Patents. r

and in one side of said frame sheet is a groove adapted to receive asensitized card or sheet, the other side of the frame sheet beingprovided at the corners thereof with pockets adapted to receive thecorners of a negative and by which said negative is held in position andpositioned with reference to the sensitized card or sheet.

In testimony that I claim the foregoing as my invention I have signed myname in presence of the subscribing witnesses this 15th day of August1912.
